[0002] Water shortage and water pollution are two major problems facing the world's water environment today, and they are receiving more and more attention and concern from all over the world. With the rapid development of the economy, the rapid growth of the population, the increasingly frequent human social activities and the continuous expansion of the scale of enterprises, a large amount of domestic sewage, organic matter, heavy metals and other toxic and harmful pollutants continue to enter rivers and lakes, and the problem of water pollution is becoming more and more serious. Many water sources have suffered sudden or gradual water pollution. In particular, major sudden water pollution accidents have brought serious disasters to human survival and the ecological environment. Continuous, effective and rapid monitoring of the water environment is an important prerequisite for preventing and controlling water pollution.

[0003] Existing drone-mounted water quality monitoring devices are generally suspended from drones and monitor in the air. However, when the trees on both sides of the river are relatively lush, the branches of the trees may cause the drone to be hit. When the drone rises to avoid these low branches, as the flight altitude increases, the interference from other environmental factors will also increase. At the same time, water quality monitoring from a higher altitude may affect the collection of water quality data due to the increased distance from the water surface, which may in turn reduce the accuracy and reliability of monitoring. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a water quality monitoring device carried by an unmanned aerial vehicle (UAV) to solve the technical problem of reduced data monitoring efficiency caused by tree obstruction.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a water quality monitoring device mounted on a drone, comprising a drone body, the bottom of which is fixedly connected to a height adjustment mechanism, the height adjustment mechanism comprising a console, a lifting motor being fixedly connected to the bottom corner of the console via a mounting ring, a pull rope being wrapped around the output end of the lifting motor, the bottom end of the pull rope being fixedly connected to a mounting block, a pan-tilt head being engaged with the interior of the mounting block, and one end of the pan-tilt head being fixedly connected to a monitoring device.

[0006] By adopting the above technical solution, the height adjustment of the monitoring device can be achieved through the height adjustment mechanism fixedly connected to the bottom of the drone body, allowing the drone to flexibly adjust the height of the monitoring device according to actual needs during flight to adapt to different monitoring environments and needs.

[0007] Furthermore, fixed landing gears are fixedly connected to the bottom corners of the drone body, four fixed landing gears are provided, and cross bars are fixedly connected between four adjacent fixed landing gears.

[0008] By adopting the above technical solution, the fixed landing gear fixedly connected at the bottom corners of the drone body provides stable support for the drone, allowing the drone to remain stable during takeoff and landing, effectively preventing the drone from tilting or overturning, thereby improving the safety of the drone.

[0009] Furthermore, a fixing ring is fixedly connected to the inner side of the four cross bars, and a support ring is provided below the fixing ring.

[0010] By adopting the above technical solution, the fixing ring fixedly connected on the inner side of the four cross bars provides a stable connection point for the protective film, ensuring that the protective film can be smoothly opened. In addition, the fixing ring can effectively disperse and withstand the load during the take-off and landing process, thereby protecting the drone body from excessive stress.

[0011] Furthermore, a plurality of the support rings are provided, and the plurality of support rings are linearly and equidistantly arranged, and protective films are adhered to the outer sides of the plurality of support rings.

[0012] By adopting the above technical solution, by providing multiple support rings and arranging them linearly and equidistantly, multi-point support is provided for the protective film, which can form support more evenly, thereby enhancing the stability of the entire device.

[0013] Furthermore, the top of the protective film is fixedly connected to the fixing ring, and the bottom of the protective film is fixedly connected to the mounting block.

[0014] By adopting the above technical solution, the top of the protective film is fixedly connected to the fixing ring, thereby ensuring the stability and fixation of the protective film, and effectively preventing the protective film from falling off during flight.

[0015] Furthermore, the lifting motor is fixedly connected to the console via a wire.

[0016] By adopting the above technical solution, the lifting motor is fixedly connected to the console through wires, ensuring that the console can accurately control the operation of the lifting motor. Through this connection method, the console can send instructions to accurately adjust the speed and direction of the lifting motor, thereby achieving height adjustment of the monitoring device.

[0017] Furthermore, a retractable landing gear is fixedly connected to the bottom corners of the drone body.

[0018] By adopting the above technical solution, the retractable landing gear fixedly connected at the bottom corners of the drone body can provide stable support during takeoff and landing of the drone, allowing the drone to adapt to different terrains and takeoff conditions, ensuring the safety and stability of the take-off and landing process.

[0019] In summary, the present invention has the following beneficial effects:

[0020] 1. This utility model, by providing a drone body and a height adjustment mechanism, can quickly and flexibly bring the monitoring equipment to the air above the river channel that needs to be monitored, thus achieving efficient water quality monitoring.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] The following describes an embodiment of the present invention based on its overall structure.

[0030] Example 1:

[0031] A water quality monitoring device carried by a drone, such as Figure 1-Figure 4 As shown, it includes a drone body 1, and a height adjustment mechanism 2 is fixedly connected to the bottom of the drone body 1. The height adjustment mechanism 2 includes a console 201. A lifting motor 203 is fixedly connected to the bottom corner of the console 201 through a mounting ring 202. A pull rope 204 is wrapped around the output end of the lifting motor 203, and the bottom end of the pull rope 204 is fixedly connected to a mounting block 205. A gimbal 206 is engaged inside the mounting block 205, and one end of the gimbal 206 is fixedly connected to a monitoring device 207. The height adjustment mechanism 2 fixedly connected to the bottom of the drone body 1 can realize the height adjustment of the monitoring device 207, allowing the drone to flexibly adjust the height of the monitoring device 207 according to actual needs during flight to adapt to different monitoring environments and requirements. At the same time, the lifting motor 203 controls the lifting and lowering of the mounting block 205, the gimbal 206 and the monitoring device 207 through the pull rope 204, making the height adjustment more precise and controllable, improving the accuracy and efficiency of water quality monitoring, and enhancing the control ability of the drone in complex environments.

[0032] See Figure 1 、 Figure 2 and Figure 3The bottom corners of the drone body 1 are fixedly connected with fixed landing gears 3, and there are four fixed landing gears 3. A cross bar 4 is fixedly connected between the four adjacent fixed landing gears 3. The fixed landing gears 3 fixedly connected at the bottom corners of the drone body 1 provide stable support for the drone, so that the drone can remain stable during takeoff and landing, effectively preventing the drone from tilting or overturning, thereby improving the safety of the drone. At the same time, the four adjacent fixed landing gears 3 are fixedly connected by the cross bar 4, which further enhances the overall stability and load-bearing capacity of the landing gear, can withstand the weight of the drone, and can also provide an installation site for the fixing ring 5 to ensure that the mounting ring 5 can remain fixed.

[0033] See Figure 1 、 Figure 2 and Figure 3 A fixing ring 5 is fixedly connected to the inner side of the four cross bars 4, and a support ring 6 is provided below the fixing ring 5. The fixing ring 5 fixedly connected to the inner side of the four cross bars 4 provides a stable connection point for the protective film 7, ensuring that the protective film 7 can be smoothly opened, and the fixing ring 5 can effectively disperse and withstand the load during the take-off and landing process, thereby protecting the drone body 1 from excessive stress. At the same time, the support ring 6 may be fixed to the protective film 7 to provide additional support and stability to prevent accidents during the monitoring process, which helps to protect key components from damage.

[0034] See Figure 1 、 Figure 2 and Figure 3 , there are multiple support rings 6, and the multiple support rings 6 are arranged linearly and equidistantly. The outer sides of the multiple support rings 6 are adhered with protective films 7. By providing multiple support rings 6 and arranging them linearly and equidistantly, multi-point support is provided for the protective film 7, which can form support more evenly, thereby enhancing the stability of the entire device. At the same time, the outer sides of the multiple support rings 6 are adhered with protective films 7, which can effectively prevent branches and willow branches in the external environment from hooking the support rings 6 and the pull rope 204. Therefore, the protective film 7 acts as a protective layer to ensure that the drone can work continuously and stably when performing water quality monitoring tasks.

[0035] See Figure 1 、 Figure 2 and Figure 3 The top of the protective film 7 is fixedly connected to the fixing ring 5, and the bottom of the protective film 7 is fixedly connected to the mounting block 205. By fixedly connecting the top of the protective film 7 to the fixing ring 5, the stability and fixity of the protective film 7 are ensured, and the protective film 7 is effectively prevented from falling off during flight. At the same time, the bottom of the protective film 7 is fixedly connected to the mounting block 205, which further enhances the stability of the protective film and realizes the stretching operation of the protective film 7, so that the lifting and lowering of the height adjustment mechanism 2 can drive the protective film 7 to unfold.

[0036] See Figure 1 、 Figure 2 and Figure 3 The lifting motor 203 is fixedly connected to the console 201 through the wire 208. The lifting motor 203 is fixedly connected to the console 201 through the wire 208, ensuring that the console can accurately control the operation of the lifting motor. Through this connection method, the console can send instructions to accurately adjust the speed and direction of the lifting motor, thereby realizing the height adjustment of the monitoring device 207. At the same time, the connection of the wire 208 also ensures the stable transmission of power and signals, so that the entire height adjustment mechanism 2 can work stably and reliably, thereby improving the degree of automation and ease of operation of the UAV-mounted water quality monitoring device.

[0037] The implementation principle of the present invention is as follows: first, the pan / tilt head is inserted into the interior of the mounting block 205 to complete the installation of the device, and then the drone body 1 is started and the drone body 1 brings the monitoring device 207 into the air. The monitoring device 207 monitors the river channel. At this time, the protective film 7 and the support ring 6 are retracted between the fixing ring 5 and the mounting block 205;

[0038] When the trees on both sides of the river block the river, making it impossible for the drone body 1 to fly near the river, the height adjustment mechanism 2 is activated, the console 201 sends a signal, and the driving motor 203 releases the pull 204, so that the mounting block 205 and the bottom gimbal 206 and the monitoring device 207 descend to the air near the river surface. In this process, the protective film 7 is gradually unfolded from the retracted state, and cooperates with the support ring 6 to protect the pull line 205 to prevent branches or willow branches from getting caught on the pull line 204, causing the drone body 1 to fall.

[0039] Example 2:

[0040] See Figure 4 The retractable landing gear 8 is fixedly connected to the bottom corners of the drone body 1. The retractable landing gear 8 fixedly connected to the bottom corners of the drone body 1 can provide stable support when the drone takes off and lands, so that the drone can adapt to different terrains and take-off conditions, ensuring the safety and stability of the take-off and landing process. At the same time, during the flight of the drone, the retractable landing gear can be retracted to reduce the occupied space and facilitate the free rotation of the gimbal 206, thereby improving its practicality and adaptability.

[0041] The implementation principle of the present invention is as follows: first, by retracting the landing gear 8, the landing gear will not interfere with the normal movement of the gimbal 206 during flight, thereby improving the flexibility of the monitoring device.
